\ snrnnaron To all-whom it may (50mm '"Be-it' known that I, GIIQBERTCALD- 'ments-in separators and hasrelation more particularly to a deviceofg'this' general character especially designed and "adapted for use inconnectionwith cotton seed; and it is an object of my invention toprovide a separator of this general character. having novel'and improvedmeans whereby-black 1101" faulty seedstogetlierl'withall dirt and looselintersx'm'ay be separated from: the

The invention-consists inthe' det'ails of construction and inthecombination :andarrangement of the several parts'of my 1mfprove'dseparator whereby certain. important advantages "are attained and thedevice. its-(renderedsim-pler, less, expenslvf'e and,

Specification of Letters Patent.

Application filed June 12, 1915. Serial at. 33,783,

v v Patented net. 2c, 1915.

The opposed -faces of the panels '1 adJacent their upper extremities areprovided with the supports 6 with which are engaged the extremities ofthe perforate screen 7 preferably formed of reticulated material ofpredetermined mesh; and of semi-circular formation in cross section,vsaid screen being disposed longitudinally on a predeter- 'mined inclinewith its vlower end portion provided with the laterally disposedextension-8 also preferably formed of reticulated material and coactingwith the adjacentend panel 1 to aiford a disehargespout for theplantingseed.

The'upper plate 2 adjacent the elevated extremity of the screenislprovided with a feedopening 9 surrounded by a. hopper 10 of desireddimensions and into which the seeds to be separated are initiallydeposited as required. Operatively supported by the end panels ,1 anddisposed through the chamber afforded by-the screen]? is the shaft 11,the opposite extremities of which extendv exteriorly beyondthe endpanels 1, one

of said extreniitiesghaving secured thereto abalance wheel 12' while theopposite ex-' tremity is operatively' engaged a s at 14, with a suitablesource of power, said power beinghereinv disclosed as a manuallyoperated drum 15 engaged with the shaft 11 through the medium of abelt16. I wish tostate, however, that it is not my desire to'llimit myselfto anyspecific meansfor' ;imparting the requisite axial rotation to theshaft 11.

The shaft'll- 'i'ntermediate the panels 1 and substantially entirelybridging the space betweensaidipanels has affixed thereto a drum orroller 17' from which radiate thespirally arranged fingers or blades 18which serve to'assure the requisite travel of the seed to beseparateddownwardly over the screen 7 to the discharge spout thereof and, 1 as isbelieved to b e self-'evident, said fingers 'orblades 18 also serves vasan agitating means for the seednwhereb'y the reflected separationthereof'isl'facilitated. I alsbifind it of advantage to connect theupper side margins of the panels 1 by the str1ps"1 9 and to which is"directly secured'the longtudinal margins. of the screen 7, I alsofind yit of advantage to provide the end panels 1 with the supporting members2.0 whereby the" samemay be effectively maintained in an operativeposition.

From the foregoing description," it is thought to be obvious that aseparator constructed in accordance with my invention is of an extremelysimple and comparatively invention is susceptible of some change andmodification Without material departure from-the'principles and spiritthereof and for this reason-l do notwish to be understood as limitingmyself to the precisearrangement and formation of the .several {partshereinshown incarrying out-my 15 vention in practice.

I claim: t A device of the class described compr1singra trough,including end panels extendingabove the trough proper, one of said endpanels having an opening therein to afford a communication within thetrough,

spout thereofv at its lower extremity, an

agitating means coactlng' with the screen element. S

y In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses.
